How can an organization securely grant a third-party application access to specific OCI resources?

To securely grant a third-party application access to specific Oracle Cloud Infrastructure (OCI) resources, the recommended approach is to configure the application to use Instance Principal. This method allows the application to authenticate directly with OCI services without needing to manage sensitive credentials like passwords or API keys.

Instance Principals: Enable compute instances to directly make API calls against OCI services, inheriting permissions through IAM policies. This setup is more secure than sharing user credentials, as it avoids hardcoding credentials within the application and leverages OCI's native security features.
